I just hit a parked car (I did not do a hit and run i waited and hour for the people to come to there car) I was trying to pull around a bend into a front row spot i thought i cleared the car that was next to mine. Unfortunately, my depth perception was wayyyyy of! Because i drive a big truck it was hard to judge the distance between my car and the tiny little car that i hit. I then hit the car and the energy from my car was transferred from my car to the tiny car. The tiny car then moved after

Some people say that my dog is over weight. But she isn't it is just her body type because she is a chiwawa beagle mix! Anyways my dog Lucy has the acceleration of a lawn mower, a squirl with 3 legs could probably out run her. I believe that gravity is what is weighing down on Lucy not the extra cookies. The force of gravity weighing down on Lucy is roughly 10 newtons (Dan Duguay told me). Gravity is not Lucy's friend. Her little legs have a hard time moving on there own. The photo attached is a

I like to make connections when i learn something because it helps me remember! when we were learning about sonar in class i automatically thought of bats. I went home and ask my dad about bats and their sonar. Bats are nocturnal animals this means that they are awake at night and sleep during the day. Because they hunt at night they need to use a sonar to find there prey. Bats use their echolocation which is a navigation sonar like system so they know when to drive down and catch their prey! Ba

First off a wave is the disturbance that transfers energy from place to place. The crest is the highest point on a transverse wave. The trough is the lowest point of the wave. The Compressions are the parts of the longitudinal wave that are closest together. Rarefactions are the parts of the wave that are closest together. Amplitude is the maximum distance from the rest position that the medium moves in a wave. The wavelength is the distance between two parts of a wave. The interference is when

Frequency of a wave is the number of times something happens divided by the time it takes. A frequency is messured in hertz one hertz is equal to one wave per second. a frequency is also found by taking 1 over the period a period is the time needed for one complete cycle of vibration to pass a given point. As the frequency of a wave increases, the period of the wave decreases. The Period equals the Total time divided by the Number of cycles. An example of a period is The period of orbit for the

Waves are everywhere sound, water and even stadium waves. My favorite type of wave however is a transverse wave. These waves are very interesting. In transverse waves the displacement of the medium is perpendicular. Perpendicular waves intersect and create a right angle. An example of a transverse wave is a ripple in a pond. Transverse waves can occur through a liquid on a string an even throughout a solid. Another type of transverse wave is light! Light contains transverse waves where the elect

A Resistance is the degree to which a substance or device opposes the passage of an electric current, causing energy dissipation. Ohm's law resistance is equal to the voltage divided by the current.
a resistor or other circuit component that opposes the passage of an electric current. Resistance is measured in Ohm's. Resistance is equal to the V (voltage) over I (current) R=V/I. Voltage is Measured in Volts and I the current is measured in amps. Resistance also equals (resistivity)(Length)/ Pi

After taking the practice midterm I realized i need to know my conventions with the metric system. My dad is very good at these things so he helped me out.
100 millimeter is a centimeter
100 centimeters is a meter
100 meters is a kilometer
30.5 centimeters in a foot
1 meter is 3.2 feet
1 yard is just about 1 meter
1 mile is about 1.6 kilometer
1 football field is 100 yards
1 football field is 91.5 meters
12 inches is 1 foot
3 feet is a yard
36 inches is a yard
about 30 c

Kinetic energy is he energy of motion. An object that has motion - whether it is vertical or horizontal motion - has kinetic energy. KE or kinetic energy is equal to 1/2 mass (m) times the velocity (v)^2. this equation reveals that the kinetic energy of an object is directly proportional to the square of its speed.Their are 3 forms of Potential energy.. The Potential energy is the energy is the stored energy of position possessed by an object. The equation to find potential energy of a spring 1

Work is presented as the letter W. The rate of work is considered the power. Work is equal to Force(F) multiplied by displacement(D). The work is also equal to the Force times the distance times cosx ... x in this case is the angle created by the force and the displacement. Work is also equal to the MAD the mass times displacement x acceleration. Work is measured in Joules a rule is a newton times a m this is also equal to kgm^2/s^2. when someone thinks they are putting a lot of work into movi

springs are everywhere, for your favorite childhood toy the slinky to clicking your pen as an adult to sign a bill. No matter what kind of spring it is or how it is being used doesn't matter when trying to calculate the spring force. The spring force is the force put on the string eating it to stretch or contract from equilibrium. Equilibrium is when forces are at balance and the spring is in its happy place. The spring force (Fs) is equal to the spring Constant(K) times the Displacement(X). The

when we first started the work power energy unit. I asked my dad what power is... he said that power is strength and speed. After completing this unit I have to say my family is sadly wrong. Power is the work put in times the amount of time it took. P=W/t. for example if you Do 20 N of work in 20 sec you only excreted 1 watt of power. I bet your wondering WATT a watt is? A watt is A watt is the unit of measure for calculating the power of a circuit. A single watt (W) is equivalent to one joule (

Newton's laws are everywhere in soccer. For example, at kick off, the ball is at rest until the whistle is blown then the player foot Is the net force creating the ball to move. Any move or change in direction a player does with the ball is also Newton's first law because it states an object in motion will remain in a straight line unless acted upon by a new force. if you were to draw a free body diagram for a soccer ball at rest would have a gravitational force (mg) pulling down on it, Fn pull

This Thursday we launched catapults. Are catapult averaged a distance of about 5 meters. When we completed the catapult at my house we thought it was really good however once at the school, are catapult seemed to be one of the underdogs. Something's I would do differently in building my catapult next time is to really take in to consideration of my catapult launch angle. an ideal launch angle to have is 45 degrees. This angle give you the maximum distance. Are launch angle was in the 70's I beli

What did the physicist snack on during lunch?
A 'gram' cracker.
I thought this was a really funny joke...I really like jokes. But I like physics even more. In physics I learned that a gram is a metric unit of mass equal to 0.001 kilograms, the basic unit of mass in the metric system.
A gram can be abbreviated as a g...make sure you don't get this confused with g as in the gravitational force of acceleration on earth. this is 9.81 m/s^2. Make sure you don't forget your units!! We u
